MaxBin, an automated software program for binning the genomes of individual microbial species from metagenomic sequences is available on-line through JBEI.

MaxBin is an automated software program for binning the genomes of individual microbial species from metagenomic sequences developed at the Joint BioEnergy Institute (JBEI).

On the Road to Artificial Photosynthesis

This TEM shows gold–copper bimetallic nanoparticles used as catalysts for the reduction of carbon dioxide, a key reaction for artificial photosynthesis.

New experimental results have revealed the critical influence of the electronic and geometric effects in the carbon dioxide reduction reaction.

Berkeley Lab Report Quantifies the Financial Impacts of Customer-Sited Photovoltaics on Electric Utilities

solar-panels-1024x682

A new report prepared by analysts from Berkeley Lab examines the potential impacts of customer-sited solar photovoltaics (PV) on electric utility profitability and rates. The report shows that these impacts can vary greatly depending upon the specific circumstances of the utility and may be reduced through a variety of regulatory and ratemaking measures.

Excitonic Dark States Shed Light on TMDC Atomic Layers

Berkeley Lab researchers have found evidence for excitonic dark states in monolayers of tungsten disulfide that could explain the unusual optoelectronic properties of single atomic layers of transition metal dichalcogenide (TMDC) materials.

Berkeley Lab researchers believe they have uncovered the secret behind the unusual optoelectronic properties of single atomic layers of TMDC materials, the two-dimensional semiconductors that hold great promise for nanoelectronic and photonic applications.

Advanced Light Source Sets Microscopy Record

Ptychographic image using soft X-rays of lithium iron phosphate nanocrystal after partial dilithiation. The delithiated region is shown in red.

Working at Berkeley Lab’s Advanced Light Source (ALS), researchers used “soft” X-rays to image structures only five nanometers in size. This resolution is the highest ever achieved with X-ray microscopy.

A Metallic Alloy That is Tough and Ductile at Cryogenic Temperatures

Rob Ritchie alloys Thumb

A multi-element high‐entropy alloy not only tests out as one of the toughest materials on record, but, unlike most materials, the toughness as well as the strength and ductility of this alloy actually improves at cryogenic temperatures.

Peptoid Nanosheets at the Oil/Water Interface

Peptoid nanosheets are among the largest and thinnest free-floating organic crystals ever made, with an area-to-thickness equivalent of a plastic sheet covering a football field. Peptoid nanosheets can be engineered to carry out a wide variety of  functions.

Researchers at Berkeley Lab’s Molecular Foundry have developed peptoid nanosheets that form at the interface between oil and water, opening the door to increased structural complexity and chemical functionality for a broad range of applications.
